Technical Field

[0001] This utility model relates to the field of AGV vehicle body technology, and in particular to an AGV vehicle body rear shell disassembly device. Background Technology

[0002] AGV is an abbreviation for "Automated Guided Vehicle," generally known as an automated guided vehicle or unmanned transport vehicle. It is a type of logistics transportation equipment that relies on computer control systems, sensor technology, and navigation technology to achieve autonomous operation. AGVs are typically used in factory workshops, warehousing centers, or docks to complete the handling of materials, parts, or goods through pre-set routes or intelligent scheduling systems. Compared to traditional manual handling, AGVs can significantly improve transportation efficiency, reduce labor costs, and minimize safety hazards caused by human operation.

[0003] Currently, existing AGVs often face the problem of limited space in practical applications: as shown in the figure, their main control center and electrical control box are usually located under the platform. During routine maintenance or hardware replacement, it is necessary to remove the lower side panel located at the bottom or lower side of the vehicle body. This lower side panel is connected to the vehicle body with a large number of fixing screws. The disassembly process is not only complicated and time-consuming, but also prone to stripping screw threads, damage to threads and corrosion in frequent maintenance or harsh environments, further increasing the difficulty of disassembly and assembly and reducing maintenance efficiency. At the same time, the cumbersome disassembly process also increases the labor intensity and operational risks of maintenance personnel, affecting the availability of AGVs and the speed of on-site operation and maintenance response.

[0004] Therefore, optimizing the disassembly method of the lower side panel from a hardware structure perspective, reducing reliance on screws during disassembly and assembly, and improving operational convenience and maintenance efficiency have become urgent technical problems to be solved in this field. Based on this, we propose an AGV rear shell disassembly device. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Refer to Figures 1 to 4 This utility model provides an embodiment of an AGV vehicle body rear shell disassembly device, including a vehicle body 1. An inner panel groove 2 is formed on one side of the vehicle body 1. A component groove 3 is formed inside the inner panel groove 2. A lower side plate 4 is installed inside the inner panel groove 2. An adjusting cover plate 5 is hinged to the outer side of the lower side plate 4. A locator 6 is also provided on one side of the adjusting cover plate 5. The lower side plate 4 and the inner panel groove 2 are structurally matched. First fixing holes 7 are formed on both sides of the lower side plate 4 and the inner panel groove 2. A maintenance window 8 is formed through the middle of the lower side plate 4. The maintenance window 8 and the component groove 3 are structurally matched. A limit ring 9 is also provided inside the maintenance window 8. The AGV rear shell disassembly device uses an adjustment cover 5 installed on the outside of the lower side plate 4. The adjustment cover 5 is hinged to the lower side plate 4 and is opened and closed and fixed by the cooperation of the positioner 6, the second fixing hole 14 and fasteners such as the telescopic bolt. When the control center or electrical control box installed in the vehicle body 1 needs to be repaired or replaced, since these components are installed in their respective component slots 3, the operator only needs to open the corresponding adjustment cover 5 without disassembling the entire lower side plate 4 to complete the repair or replacement operation conveniently. This repair process avoids frequent disassembly and assembly of the screws between the vehicle body 1 and the lower side plate 4.

[0026] An inner liner 10 is installed on the inner side of the adjusting cover 5. An embedded groove 11 is formed on the outer side of the adjusting cover 5 and the inner liner 10. Several sets of elastic protrusions 12 are also provided on both sides of the inner wall of the inner liner 10. By adding the inner liner 10 to the inner side of the adjusting cover 5 and forming the embedded groove 11, and by providing the elastic protrusions 12 on both sides of the inner wall of the inner liner 10, the stability and sealing between the adjusting cover 5 and the maintenance window 8 in the closed adjustment state can be improved, achieving reliable locking and protection during operation. A rectangular groove 13 is provided through one side of the limiting retaining ring 9. A second fixing hole 14 is provided on one side of both the limiting retaining ring 9 and the adjusting cover 5. Arc-shaped grooves 15 are also provided on both sides of the inner wall of the limiting retaining ring 9. By providing the rectangular groove 13 through one side of the limiting retaining ring 9, and The second fixing hole 14 opened on one side of the limiting retaining ring 9 and the adjusting cover plate 5, and the arc-shaped grooves 15 provided on both sides of the inner wall of the limiting retaining ring 9, can realize the reliable snap-fit ​​and limiting fixation between the adjusting cover plate 5 and the limiting retaining ring 9, ensuring that the adjusting cover plate 5 maintains a stable position during opening or closing. At the same time, it facilitates the quick connection between the telescopic screw and the second fixing hole 14, achieving convenient operation, accurate positioning and structural stability during maintenance. The embedded retaining groove 11 and the limiting retaining ring 9 are in a transition fit, and the arc-shaped groove 15 and the elastic protrusion 12 are in a snap-fit ​​fit. Through the structural design of the transition fit between the embedded retaining groove 11 and the limiting retaining ring 9, and the snap-fit ​​fit between the arc-shaped groove 15 and the elastic protrusion 12, the stability and sealing of the closing adjustment between the adjusting cover plate 5 and the maintenance window 8 can be improved.

[0027] Positioner 6 includes a connecting shaft 16, which is rotatably connected to the middle of one side of the adjusting cover plate 5. An adjusting knob 17 is mounted on one end of the connecting shaft 16. A compression spring 18 is sleeved on the outer side of the end of the connecting shaft 16 near the adjusting knob 17. A rectangular block 19 is also provided on the end of the connecting shaft 16 away from the adjusting knob 17. Through the cooperation of the connecting shaft 16, adjusting knob 17, compression spring 18, and rectangular block 19, the positioner 6 allows the adjusting cover plate 5 to be opened or closed at the corresponding component slot 3 opening without the need for screw fixing. This structural design enables the AGV vehicle body to achieve rapid opening and closing of the adjusting cover plate 5 and component slot 3 by rotating the positioner 6. The rectangular block 19 and the rectangular groove 13 are structurally matched, and there is a transition fit between the rectangular block 19 and the rectangular groove 13. Through the transition fit structure design between the rectangular block 19 and the rectangular groove 13, when the rectangular block 19 and the rectangular groove 13 are aligned, the rectangular block 19 installed at one end of the connecting shaft 16 can be connected to the side center of the limiting ring 9 through the rectangular groove 13. When the rectangular block 19 is adjusted by rotating the adjusting knob 17, the position of the rectangular block 19 and the rectangular groove 13 can be offset. The offset rectangular block 19 is limited by the elastic compression of the compression spring 18, thereby ensuring the reliable fixation of the adjusting cover 5 in the open or closed state, realizing quick adjustment, stable positioning and convenient maintenance during operation.

[0028] Working Principle: This design proposes an AGV vehicle body rear shell disassembly device. By adding an adjustment cover plate 5 to the outside of the lower side plate 4, the adjustment cover plate 5 is hinged to the lower side plate 4. With the help of the positioner 6, the second fixing hole 14, and bolts and other fasteners, the opening and closing adjustment and fixation of the adjustment cover plate 5 can be achieved. When the control center and electrical control box installed on one side of the vehicle body 1 need to be repaired or replaced, it is not necessary to completely disassemble the lower side plate 4. The repair work can be completed simply by opening the corresponding position of the component slot 3 through the adjustment cover plate 5. This maintenance process avoids frequent disassembly and assembly of the screws between the vehicle body 1 and the lower side plate 4, thereby effectively preventing problems such as stripping, thread damage and corrosion of the screws due to long-term maintenance or harsh environment.

[0029] When the adjusting cover 5 is closed and adjusted to the opening of the component slot 3, the transition fit between the embedded retaining groove 11 and the limiting retaining ring 9, as well as the snap-fit ​​fit between the arc-shaped groove 15 and the elastic protrusion 12, allows the adjusting cover 5 in the closed state to be reliably snap-fitted and positioned inside the maintenance window 8. At the same time, this structure also improves the sealing between the adjusting cover 5 and the component slot 3, preventing external dust or impurities from entering the control center. Through the snap-fit ​​fit between the arc-shaped groove 15 and the elastic protrusion 12, the limiting retaining ring 9 and the second fixing hole 14 opened on one side of the adjusting cover 5 can also limit the movement, facilitating the connection and fixation of the telescopic screw and the two sets of second fixing holes 14. This design allows the operator to operate with one hand without having to support the adjusting cover 5 with one hand and tighten the screw with the other during the assembly process, significantly improving the convenience of actual operation.

[0030] The locator 6, located on one side of the adjusting cover plate 5, is composed of a connecting shaft 16, an adjusting knob 17, a compression spring 18, and a rectangular block 19. It forms a transition fit with the rectangular groove 13. When the adjusting cover plate 5 is opened or closed at the opening of the component groove 3, this structure can quickly open and close the adjusting cover plate 5 without relying on traditional screws for fixing, simply by rotating the locator 6. This design not only shortens the operation time and simplifies the operation process, but also significantly improves the flexibility and practicality of the AGV vehicle body rear shell disassembly device during use, providing an effective guarantee for the reliable operation of the AGV vehicle body in frequent maintenance and complex application scenarios.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
